So Arsene Wenger could well look to strengthen in January given the frustrations he suffered during the summer, even though it is a window he often criticises due to the high prices that are quoted for players.

But the bookies believe Wenger could be busy as we move into 2018 - with Arsenal favourites to sign Sergio Aguero from Manchester City.

With Pep Guardiola expected to make another move for Sanchez, it could be that Aguero falls into the mix as a makeweight - something that could appeal to the Argentine if he has been struggling for game time ahead of the World Cup.

SkyBet list Arsenal as 10/1 favourites to sign Aguero, while Sanchez is quoted at 4/1 to move in the opposite direction.

And the odds on Thomas Lemar finally competing a switch to the Emirates in January are as short as 6/1 - despite the French winger having turned down a move to north London last week.

The prospect of Sanchez walking away for nothing in less than a year’s time is now a very real one after the Gunners pulled the plug on a deadline day move to Manchester City.

Should they resist any more offers in January, the 28-year-old will almost certainly leave on a free - with the former Barcelona man having made it clear he will not be signing a new deal in north London.
